Satsuma Harvest Season in North Florida

When asked what kind of citrus to grow here in North Florida, my default response is satsuma. I usually get a funny look, followed by an attempt by the person who’s asking to repeat the name satsuma. The individual may ask, “What is satsuma… is that a citrus?” I guess the person expected to hear orange, grapefruit, lemon or maybe tangerine.
Satsuma is a type of citrus, technically classified as a mandarin and is sometimes referred to as satsuma mandarin. The satsuma mandarin is a good candidate for the North Florida citrus enthusiast for a number of reasons.
- Historically, mature dormant trees have survived minimum temperatures of 14°F to 18°F when budded/grafted to a cold-hardy rootstock such as trifoliate orange or swingle, a trifoliate orange cross. Young trees are not as cold-hardy but, due to their smaller size, are more easily covered with a cloth such as a sheet or lightweight blanket for protection during freezes.
- Satsuma fruit are ready to harvest October through December, ripening before the coldest winter temperatures. This is not true with most sweet citrus types such as oranges, which are harvested during winter months. Harvesting during winter works well in Central and South Florida where winters are mild but does not work well here in extreme North Florida. The potentially colder winter temperatures of North Florida are likely to result in the fruit on sweet oranges freezing on the tree before they are ripe, potentially ruining the fruit.
- Our cooler fall temperatures result in higher sugar content and sweeter fruit.
- Fruit are easily peeled by hand, have few to no seed and are sweet and juicy.
- Trees are self-fruitful, which means that only one tree is needed for fruit production. This is important where space is limited in a home landscape.
- Trees are relatively small at maturity, reaching a mature height of 15 to 20 feet with an equal spread.
- Branches are nearly thornless. This may not be true with shoots originating at or below the graft union. Shoots coming from the rootstock may have long stiff thorns. These shoots should be removed (pruned out) as they originate.
Satsuma fruit are harvested in fall but trees are best planted during springtime when temperatures are mild and as soil is warming. Availability of trees is normally better in spring, as well. For additional cold protection, purchase a satsuma grafted on trifoliate orange rootstock and plant the tree on the south or west side of a building. There are a number of cultivars from which to choose.

Romaine: Lettuce of an Empire
Who doesn’t enjoy a fresh, crisp bowl of salad? Lettuce happens to be a vegetable that is easily grown in Florida for fall & winter gardens. In Florida, four types of lettuce are commonly grown: crisphead, butterhead, leaf, & today’s topic, romaine.

An interesting, little known fact about romaine lettuce is that it was cultivated extensively by the Roman Empire. By the fourteenth century, the Catholic Hierarchy had moved from Rome to Avignon, France bringing their prized lettuce along with them. During this period, the plant was known as “Avignon” lettuce. In England, romaine is called “cos” lettuce named after the Greek islands from which the lettuce was originally distributed. Of course, in the U.S., the name we give, Romaine, refers to the time when it was grown extensively in the Roman Empire.
Romaine is grown both commercially and in backyard gardens across the state. Like all lettuce, this is a cool season vegetable. September through March is a generally the extent of the growing season. Romaine can be grown from seeds or by transplants. If you are going the seeding route, just remember these seeds are very small and should be sown shallow and in a tight pattern, with 12”-18” row spacing and a light sprinkle of soil over the top. Newly planted seeds may require burlap or straw to help retain soil moisture for successful germination. Once plants reach a few inches in height, rows can be thinned to where plants are 8” apart.
Romaine needs adequate soil moisture throughout the season. Mulching around plants to retain moisture and adding a complete fertilizer such as 8-8-8 will help ensure a good yield. Lettuce is vulnerable to the usual suspects of garden pests. However, gardening in cooler months helps combat that threat.
Romaine lettuce is fun and rewarding to harvest, as well. You can pick a few leaves off a plant or harvest the entire head.

‘Patio Baby’: An Eggplant for Any Space
In my ongoing search for low-maintenance vegetable varieties that perform well in small spaces, like my raised bed garden, I decided to try a newish Eggplant variety called ‘Patio Baby’ this summer. Developed by PanAmerican Seed and winner of the 2014 All-American Selections Vegetable- edible category, I was drawn to ‘Patio Baby’ due to the advertising claims made that it was a true miniature variety, perfect for growing in containers, only reaching 20” or so in height and producing both “early” and abundant fruit. I’ve been very pleased with the performance of this extremely unique variety so far in my informal backyard trial and definitely think it deserves consideration in your garden too!

The first observation when seeing a mature ‘Patio Baby’ is how small the plant is, leaves, flowers, fruit, everything. Compared to a standard ‘Black Beauty’ variety, ‘Patio Baby’ plants measure maybe a third as tall and wide. Where a “normal” eggplant fruit might be slightly larger than a softball and often have spines on their calyxes (the green part that connects the purple fruit to the stems), ‘Patio Baby’ fruit are roughly the size of a large chicken egg and totally spineless! I find this smaller plant and fruit size to have several perks. Vegetable plants that grow 2’ tall and wide are just about perfect for raised bed gardening. If you don’t require a large quantity of eggplant, you won’t have to sacrifice an entire bed’s space to ‘Patio Baby’ like you would with the standard varieties. Also, ‘Patio Baby’ fruit won’t bend or break branches and are held strongly on the plants, with no need for staking, another bonus when space is at a premium. Finally, I find it much easier to harvest, handle and prepare the small, spineless ‘Patio Baby’ fruit in the kitchen. Think of them as a “personal pan” eggplant. As I’m the only one in my house who eats much eggplant, I waste a lot less fruit cooking these little guys!

‘Patio Baby’ Eggplant also lives up to its reputation of being exceedingly easy and quick to grow. I purchased a packet of ‘Patio Baby’ seed from Johnny’s Selected Seeds in June and planted three in a 20” diameter decorative pot next to my raised bed garden during the first week of July, behind summer squash that had recently expired in the heat of late June. After sprouting, the plants grew strongly and, true to form for most Eggplant varieties, were bothered by no serious pest or disease issues other than the normal stinkbugs and occasional caterpillar that plague summer gardens in Florida. Around 8 weeks from sowing seed in the soil, cute, egg-shaped fruit were ready for harvest! Over the next three or four weeks, my single plant produced around 50 of the cute little fruit. More than enough for me and plenty to share, the goal of my gardening endeavors.

If you’ve run out of space in your raised bed garden, just want a single plant for your back porch or simply want to try a novelty vegetable variety, my experience this summer deems ‘Patio Baby’ Eggplant is an excellent option! For an eggplant that is space-efficient, very early and heavy producing, and comes in a more easily harvestable, kitchen-friendly package, try ‘Patio Baby’.

Clean Up for the Fall Vegetable Garden
A common question for gardeners at the end of the season is if one should till the soil or use no till practices. Opinions vary regarding this question, even among Extension Agents. However old crops harbor insects, both good and bad. This phenomenon was noticed on some recently cut back tomato plants. The intention was to cut the leftover spring garden tomatoes back to encourage fall production. Instead, a host plant for mealybugs was provided.

Mealybugs are soft-bodied insects that possess a covering of flocculent, white, waxy filaments. They are about 1/8 inch in length and usually pinkish or yellowish in color. Mealybugs have piercing-sucking mouthparts which they use to siphon fluids from the leaves, stems, and sometimes roots of many ornamental and vegetable plants. Mealybug damage produces discolored, wilted, and deformed leaves.
One very common example of an insect pest likely to claim residence in your garden’s crop residue, are squash bugs. They like to overwinter on squash, cucumber, and other cucurbit crop residue. If you choose to not till your garden and leave a portion of last seasons crop in your garden, then you should consider applying an insecticide to your spent crop at the end of the season. A product containing a pyrethrin or pyrethroid as an active ingredient would be a good broad spectrum insecticide to control any pest that may reside on plant residue. More information on pyrethrins and pyrehtroids can be found at the EPA webpage: Pyrethrins and Pyrethroids. If you choose to apply an insecticide, it is important that you follow the information on the label regarding pollinator protection. Another option is to plant a trap crop on the edge of your garden to help attract pest insects away from your desired crops. More information on trap crops can be found in the EDIS Publication: Intercropping, Pest Management and Crop Diversity.

So the answer to the till or no till question is…it depends. It is really up to the gardener. Yes, the residue from crops will add nutrients and organic matter to your soil, but it could also increase pest pressure in your garden. If you don’t plan to remove crop residue and don’t plan to till, then keep an eye out for what could be hiding in your garden.
